900 HP on Propane: More Info

In the story “900 HP on Propane” in the Dec. ’12 issue, we covered the feats of the Mothers ’70 Chevelle that makes that kind of power on that kinda fuel with a 454ci LSX engine and a Magnuson 2300 supercharger. In a follow-up note, Jim Holloway of Mothers felt that we’d made an error of omission that failed to credit two companies that made a big impact on the ability to make huge power on clean fuel.

The first is Propane Edge Group (PropaneEdgeGroup.com), which manufactures the complete liquid-propane fuel-delivery system, from tank to engine, using its Dual Jet Pump. PEG also handled the programming required to operate the twin banks of injectors for an improvement of 33 percent in power and efficiency.

Next, Jim pointed out that our description of the car having been built on a “chassis jig” was an absurd understatement given the technology involved in the Rapid Line Design Bench from a company called Rapid Line Inc. (RapidLine.com). The same company offers the design software used to fabricate the suspension and IRS for the Chevelle. Jim says, “But if not for Rapid Line, we could not have built this car in 16 weeks for HOT ROD TV. HOT ROD, Mothers, and the automotive industry at large owe these two incredible companies their due exposure for pioneering this green hot rod.”

Finally, we neglected to mention Magnaflow as the exhaust sponsor. For more, see the Chevelle at Mothers.com. To see the story on video from HOT ROD TV, visit YouTube and search for “Mothers Chevelle.”
